Model#831-287728...Can anyone help me???

I know how useful it can be to have the owners manual for your appliance so that you can troubleshoot and maintain your appliance and I will be happy to help. While you are waiting for an expert answer, I did manage to find a link that will provide you with your owners manual. I hope my link is useful.

I see that you have been given a link to the manual for you cardio fit. Please click on the link above to view the manual. You might have to wait a few moments for the manual to open depending on you internet speed. Once the manual is opened you can print a copy or save it to your computer.
